It was the first YAMAHA 4-stroke 250cc model. Compared to the 400, its tire size was only one size smaller and the chassis parts were quite the same. They made it look a bit overweight.
It was renewed from its initial square shaped style to a special design that had a tear-drop shaped tank and a staged seat. The SP version came with cast wheels.
250cc class motorcycles used to be a scaled-down version of the 400cc motorcycles, and few attracted motorcycle fans. However, this RG, specially designed as a 250cc model, became a huge hit for its high-power engine.
It underwent a full model change to be converted from DX to RD. It adopted a newly designed 7-port torque induction engine and a 6-speed transmission, which was rarely seen in those days.
It was the E-specification of the RG250, which was an ultra light 250cc model. It came with cast wheels, and improved its rigidity and reliability of its drive system.
It was the first commercially sold model to adopt an aluminum frame called AL-BOX. It came with a front 16-inch wheel, ANDF (Anti Nose Dive Fork) system, and a tight rear full floater suspension.
It was the 5th model of its series. By newly adopting a SIPC (Suzuki Intake Pulse Control) system and a SAEC (Suzuki Automatic Exhaust Control) system, its maneuverability improved drastically.
It was a model that had removed the full cowl of the GSX-R250R. Like the WOLF, the double disc of the front brake had been modified to a large-diameter single brake.
250cc version made its debut to become the youngest brother model of its series. It had the same dragger style, such as the 1490mm long wheel base and the 690mm low seat.
